feat: Introduce Debugging and Testing Guide with enhanced startup options

- Added a new document, E5-debugging-guide.md, providing comprehensive strategies for debugging and testing the `yaze` application, including logging practices and testing frameworks.
- Updated E2-development-guide.md to include a new section on debugging and testing, detailing quick debugging methods using command-line flags for specific editors and UI cards.
- Enhanced the main application to support command-line flags for opening specific editors and cards on startup, improving the developer experience.
- Refactored the Controller class to handle startup editor and card initialization based on command-line inputs.
